### Subtracting Fractions with like Denominators.

Rule for Adding or Subtracting like Denominators:

*When we say like denominators it means the same bottom numbers.*

Subtracting
Fractions with like denominators basically has the same rule as Adding Fractions with like Denominators.

When adding or subtracting fractions with like denominators you start by adding or subtracting the numerator, and the denominator stays the same.

Examples for adding Fractions with like denominators:

1/4 +1/4=2/4

Examples for Subtracting Fractions with Like Denominators:

3/4-2/4= 1/4

When simplifying your answer you first find the greatest common factor of the numerator and denominator, then divide the numerator and denominator by the greatest common factor. If you can not find a factor for the numerator and denominator then it has already been simplified to it's lowest form.

eg.
7/10-3/10= 4/10= 2/5
1/4+1/4= 2/4= 1/2
